Subject: Fix fix reference cycle in test col_accessor_map callback
X-Git-Tag: 0.07048~5
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?p=dbsrgits%2FDBIx-Class-Schema-Loader.git;a=commitdiff_plain;h=f3bed1f1082ac865772d577252a7c80af4504d4c

Fix fix reference cycle in test col_accessor_map callback

This was making the tester's DESTROY method try to reconnect to delete
tables during global destruction, causing crashes (including
segfaults).

There's still something else causing causing occasional segfaults in
XS_DBI_dispatch (called for DBI::common::DESTROY) during global
destruction.

In passing, use curry everywhere appropriate.
